The flaw in factory resets

Published

on

A new service allows users to sell old phones and tablets but, as LIRON SEGEV reports, deleting information before selling a device does not wipe your slate clean

Every phone and tablet has an option under Settings that allows you to Reset Phone to Factory Defaults. When activating this option the phone warns you that it will delete all your information, pics, music, e-mail, apps and everything else that you have loaded on the device. Essentially the phone is reset to the point where it came out of the factory and ready to be setup for the first time.

But is this good enough ? Is your information really deleted?

The shocking answer is: NO.

What happens when you delete ?

When we create a file, such as when we snap a new pic or create a new document, the operating system creates the file by storing it in bits and pieces in blocks on the device’s storage – be it internal phone storage or SD Card. It look similar to this:

In order to find which blocks make up the file, the operating system creates an index which identifies the bits that make up the complete file.

When you delete a file, the operating system removes not the content inside the blocks, but removes the reference to those blocks from the Index. However all the bits in the blocks still remain on the hard drive and are marked as “free” so that new files can overwrite those bits. It’s the equivalent of removing the chapter name from the Index of the book, but still leaving the contents of the chapter inside the book – if you page through, you will find that chapter even without the index.

And this is where the problem arrises.

There are applications that allow techies to skip over the index and view the bits inside those blocks so they can recover any file whose blocks haven’t been overwritten by new files.

Does Factory Reset leaves content behind?

Yes.

This is confirmed by the team at security firm Avast, who purchased 20 phones on eBay and ran their software though them that have been reset to Factory Defaults. They discovered over 40,000 photos (yes, including those sexting pics), 750 e-mails, 250 contacts with names and addresses and various personal files.

Stefan Tanase, Senior Security Researcher, Global Research & Analysis Team, Eastern Europe, Middle East and Africa, Kaspersky Lab confirms this too:

“A staggering amount of personal data is usually left on devices after a factory reset is performed. Most often these devices end up being sold on eBay(-like) websites, and might end up in the hands of someone with bad intentions, who can recover the data. Users don’t realise that they leave behind e-mails or SMS messages, contact information or even personal pictures and videos shot with the phone camera. Essentially, all data stored on the device is recoverable to some extent”

How do you do you ensure that your data is actually deleted ?

Simply doing a factory reset clearly is not the answer. If you want to ensure that none of your sensitive pics or information land up all over the Internet, you should Encrypt your device before doing Factory Reset

This sounds very “James-Bondy” but it s a simple step that you need to do with the tool  included with your phone. When you run the encryption tool, it protects your files from prying eyes which goes a long way to stop anyone with $50 software from getting a hold of your  family pics.

Each phone manufacturer has their own way of dealing with encryption:

Obviously before engaging in this, make sure you read and understand what is involved and back up your phone (do not lose the PIN either.)

If your device doesn’t have encryption built into the settings, then you can download several applications from the App Stores that allow you to do that.

The obvious solution would be for the mobile phone manufacturers to have encryption built into their Factory Reset process, however as Stefan Tanase  points out that the mobile phone manufacturers chose not to do this because of:

1. Lack of security awareness – both users and manufacturers generally don’t realise the importance of securely erasing data.

2. Speed – erasing a storage device securely takes more time, and the reality is that most users would rather have their device quickly perform the factory reset.

The more we trust our mobile phones with out lives, the more we should be weary of just how vulnerable these devices are. We need to be more aware of the digital fingerprints we are leaving behind.

Smart grids needed for Africa’s utilities

Power utilities across Africa should rethink their business models and how they manage and monetise their assets to keep pace with the changing energy ecosystem, says COLIN BEANEY, Global Industry Director for Asset-intensive and Energy and Utilities at IFS.

Africa’s abundant natural resources and urgent need for power mean that it is one of the most exciting and innovative energy markets in a world that is moving rapidly towards clean, renewable energy sources. The continent’s energy industry is taking new approaches to providing unserved and underserved communities with access to power, with an emphasis on smart technologies and greener energy sources.

Power systems are evolving from centralised, top-down systems as interest in off-grid technology grows among African businesses and consumers. And according to PwC, we will see installed power capacity rise from 2012’s 90GW to 380GW in 2040 in sub-Saharan Africa. Power utilities are needing to rethink their business models and how they manage and monetise their assets to keep pace with the changing energy ecosystem.

Energy and utilities providers are transforming from centralised supply companies to more distributed, bi-directional service providers. They can only achieve this through the evolution of “smart grids” where sensors and smart meters will be able to provide the consumer with a more granular level of detail of power usage. This shift from an energy supplier to “lifestyle provider” will require a much more dynamic and optimised approach to maintenance and field service.

African companies must thus embrace digital transformation as an imperative. This transformation begins by embracing enterprise asset management to improve asset utilisation. The subsequent steps are enhancing upstream and downstream supply chain management; resource optimisation; introducing enterprise operational intelligence; embracing new technologies such as the Internet of Things, machine learning, and predictive maintenance; and becoming a smart utility.

Embracing mobility to drive ROI

Getting it right is about putting in place an enterprise backbone that accommodates asset and project management, multinational languages and currencies, new energies and markets, visualisation of the entire value chain, and mobility apps. Mobile technologies that support the field workforce have a vital role to play in driving better ROI from utilities’ investments in enterprise asset management and enterprise resource planning solutions.

Today’s leading enterprise asset management solutions feature powerful functionality for mobile management of the complete workflow of work orders – from logging status changes and updates, from receiving and creating new orders to concluding the job and reporting time, material and expenses. Such solutions are easy to deploy and intuitive for end users to learn and use.

Importantly for organisations operating in parts of the continent with poor telecoms infrastructure, connectivity is not an issue. The solutions work offline and synchronises when network connectivity is available. Users can work on any device—laptops, tablets, and smartphones—commercial or ruggedised.

By ensuring that field technicians have easy access to information and processes, the mobile solution enables technicians and maintenance engineers to easily do the following tasks:

·         Create a new work order on the fly and log new opportunities

·         Access both historical and planned work information when requested

·         Permit customers to sign when the job is completed

·         Capture measurements and inspection notes on route work orders

·         Create new fault reports on routing

·         Facilitate documentation through photo capturing

·         Provide easy access to technical data and preventive actions.

The power of mobility allows the engineer to be the origin of all data capture on a service event. They can easily inquire on asset history, record parts used or parts needed for repair, record labour hours, and expenses as they occur, and any notes of repairs performed. When coupled with workforce management tools, such solutions unlock significant productivity gains for utilities who are trying to get the most from their workforce and assets.

Brands fall for app vanity

The experience of a mobile screen full of icons, representing independent apps that your need to open to experience them, is making less sense. Instead, businesses should serve customers with an ‘app-like’ experience inside the digital platform they already use, says PIETER DE VILLIERS, Group CEO at Clickatell.

Published

Many brands remain obsessed with creating mobile apps. This not only defies trends that point to increasing consumer app apathy, but can exclude a sizeable portion  of your customers in emerging economies. Companies need to engage with their users where they are rather than forcing them onto an app, in what can only be described as brand vanity. 

In 2017 there were around 2.2 million apps available in the iOS app store and over 3 million on Google Play. And, while the number of apps being downloaded continues to rise, analysis shows that consumers are only using 30 apps per month and accessing just 9 on a day-to-day basis. 

While these numbers still seem attractively high, in reality the majority of the apps we use are for messaging (like Facebook Messenger, WhatsApp, and WeChat) and our social networking, gaming, leisure, dating or utility activities. 

Despite the facts, the application strategy as the holy grail for digital transformation is still being pushed even within large progressive brands. What’s more, some advertising agencies and digital consultants are still pushing apps as the best means for companies to connect with their customers. This has resulted in some organisations stubbornly doubling down on app strategies which are simply not showing return on investment (ROI). 

It’s not immediately clear to us whether the fascination with apps is a roll-over from long overdue projects or whether brand owners equate a mobile-first strategy with a mobile app. Mobile-first in 2018 means customer first, and therefore embracing chat commerce in order to deliver services with convenience and simplicity in mind. 

Why apps won’t win the internet

The problem with apps goes beyond user fatigue. In the first instance, many apps are poorly designed, assuming technical sophistication which may not match reality for the average customer. Poor user interfaces and attempts to provide complex engagement can result in even the best ideas missing their targets due to lack of engagement. 

Secondly, we all know that economic realities drive consumer behaviour. In Africa, new mobile phone users typically opt for feature phones over smartphones. With a longer battery life and a much more accessible price point, feature phones still allow for a basic internet connection, chat platforms like WhatsApp, and call and message functionality. In these regions, the cost of an app – even if it’s free – goes far beyond installing it. Constant updates require reliable and cheap access to the internet. For the average phone owner in an emerging market, this can be a serious challenge. 

Thirdly, and most importantly, apps must be relevant to their intended market. Frequency of usage is a key measure of relevance. 

Apps which are used on a daily basis, like health and fitness trackers, enjoy constant engagement. New features which are added are eagerly awaited by users who are happy to update their apps. 

However, users may well question the relevance of the app if they are required to conduct updates on a monthly or even weekly basis when they are only making use of the app once or twice a year. 

On average, I download one app per quarter. Some I use more frequently than others, but all of these apps need to be regularly updated to maintain security, update features, and fix bugs. Many apps are pushing out updates much more frequently. I noticed over the past year that I could go from having all apps updated, to 32 apps requiring an update in five days.

When it comes to a customer-first digital strategy, companies should be asking themselves if an app is really the best way to reach their target audience. 

In fact, at the end of 2016, Gartner predicted that by 2019, 20 percent of brands would ditch their mobile app. What’s more, in its 2018 predictions, the company forecast that by 2021, more than 50 percent of corporations would spend more per annum on bots and chatbots than on mobile app development. 

So, we need to ask, what is the alternative for CIOs, CDOs, CMOs, and digital leaders who are looking for ways to reach, retain and grow their customer base? 

The logical app alternative 

The old battle advice goes: fight your enemy where they are not. Military strategists agreed that having your enemy come to you and fight you on your own terms was preferable. In a world where customers have access to thousands of offerings and millions of deals online, we need to flip that idea to Meet Your Customers Where They Are. 

Any marketeer will tell you just a how difficult it is to drive app downloads. Development, cross platform testing and user interface aside, the marketing campaign required to get customers to download the app can swallow entire annual budgets and still come up short. 

Looking at the facts, it makes infinitely more sense to work within the digital platforms already being used by your target audience. 

Clickatell is already enabling chat commerce for some of the leading global brands with its Touch solution. This allows organisations to serve their customers with an ‘app-like’ experience inside the chat or browser platform of their customer’s choice (Twitter, Facebook Messenger, etc.) 

Brands can now send an actionable Touch link such as ‘find the nearest ATM’ or ‘reset my password’ within a chat stream that will open an intuitive touch card without the user having to download an app to perform the action. Services can also be linked to the in-app experience for brands not looking to abandon their app efforts. 

Working with our clients, many of whom are global innovators and thought leaders, we’ve found that having the courage to design with an ‘end user first’ approach and dealing with the back-end complexity behind the scenes results in cost efficient customer delight and ROI.
